Description
Technical field
The utility model device is used for applying and the holdout device of minor diameter wire tensioning force.
Background technology
In reinforcing bar, steel twisted-line tension-force applying, the main method of application has jack tension method at present.Described jack tension method, usual chief component comprises pedestal, loading lifting jack, load transducer, stretching end fixture, stiff end fixture.Its operation logic is: reinforcing bar or steel strand wires are anchored on pedestal by stretching end fixture and stiff end fixture, and then carry out stretch-draw with lifting jack, accurate force value is controlled by load transducer.Loading lifting jack is a whole set of hydraulic system (specifically comprising lifting jack, oil pipe, oil pump etc.), and load transducer is a set ofly can survey the measurement mechanism (specifically comprising force cell, readout instrument etc.) reading force value in real time.Jack tension method adopts electrified equipment, easily controls stretching force, but equipment price is expensive, complex operation.
Also relate in prior art that to be applicable to km long, large diameter stretching force bringing device, Chinese invention " the pre-pulling test machine of the long wire rope of km " disclosed in the 2014.03.26, for a kind of wire rope stretcher, its structural design is:. comprise pedestal, stretching clamp and propulsion system, pedestal is provided with the fixing stretching clamp being positioned at left side and the movable stretching clamp being positioned at right side, the right side pedestal of described movable stretching clamp is fixed with bearing, propulsion system are installed with by uniform claw on the right side of bearing, the output terminal on the right side of propulsion system is connected with pressure transducer, pressure transducer is fixedly connected with the vertically disposed load top board of its right-hand member, the both sides of load top board are connected with the both sides of movable stretching clamp by symmetrical pull bar, the bottom of load top board is provided with support, support is provided with chute and is placed on the roller chain in chute, fix and be evenly equipped with several carrying rollers between stretching clamp and movable stretching clamp.This invention is used for for the harm of the twist stress of wire rope and elimination.
Utility model content
The purpose of this utility model is to provide a kind of minor diameter wire tensioning force bringing device.By leverage, the amplification of the quality of mass can be converted into stretching force and be applied to steel wire, and this force value of lasting maintenance.
The utility model needs the technical scheme of protection to be characterized by:
A kind of minor diameter wire tensioning force bringing device, it is characterized in that, device entirety is a self-equilibrating lever, and comprise base 3, column 2, lever 1, standard mass 7, a pair fixture 4, corrosive liquid container 8, described a pair fixture 4 is made up of upper fixture, lower clamp;
The bottom consolidation of described column 2 on the base 3;
Described lever 1 is in its brachium direction, movable and be limited in the top of column 2 by rotating steadying bar 9 at B point place, be hung with standard mass 7 at its C point by counter-balanced carriage 5, fixture on its A point place is hinged by rotation axis 10, the horizontal length between BC is greater than the horizontal length between AB;
Described upper fixture, lower clamp are vertically corresponding, and lower clamp is articulated with on base 3 by rotation axis 10;
Measurand steel wire 6 two ends are individually fixed between fixture, lower clamp, and steel wire 6 penetration corrosion liquid container 8, part Steel Wire Surface is immersed in corrosive liquid.
The utility model entirety is a self-equilibrating lever, without the need to extraneous stationary installation, special wire clamp is adopted to be fixed on device by steel wire two ends, then by counterweight, stretching force is applied to steel wire, can be easy to steel wire apply setting force value and can be lasting maintenance force value, corroded by the part surface of the corrosive liquid in container to steel wire on this basis, carry out the corrosion test of pierce tap stress.The energy is not consumed, low-carbon environment-friendly during test duration.
Accompanying drawing explanation
Fig. 1 is device organigram.
Embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further described.
As shown in Figure 1, the utility model discloses a kind of minor diameter wire tensioning force bringing device based on lever principle, device entirety is a self-equilibrating lever, comprise base 3, column 2, lever 1, standard mass 7, a pair fixture 4, corrosive liquid container 8, described a pair fixture 4 is made up of upper fixture, lower clamp;
The bottom consolidation of described column 2 on the base 3;
Described lever 1 is in its brachium direction, movable and be limited in the top of column 2 by rotating steadying bar 9 at B point place, be hung with standard mass 7 at its C point by counter-balanced carriage 5, fixture on its A point place is hinged by rotation axis 10, the horizontal length between BC is greater than the horizontal length between AB;
Described upper fixture, lower clamp are vertically corresponding, and lower clamp is articulated with on base 3 by rotation axis 10;
Measurand steel wire 6 two ends are individually fixed between fixture, lower clamp, and steel wire 6 penetration corrosion liquid container 8, part Steel Wire Surface is immersed in corrosive liquid.
Specifically, counter-balanced carriage 5 is connected to the C point of lever 1 by rotation axis 11, and standard mass 7 is positioned on counter-balanced carriage 5.
Principle of work: standard mass is under gravity by counter-balanced carriage and through the conversion of leverage and amplification, the stretching force of needs is applied on the steel wire be fixed on fixture, and stably keep force value constant within the time continued, the part surface of corrosive liquid meanwhile in container to steel wire corrodes, thus realizes the corrosion test of pierce tap stress.
